Also added support to delegates with up to 8 params
out of whatsnet:
note that old code did not take care of mem_mask
that caused me troubles debugging this

This is just a point-in-time, "it compiles and seems to work
like before" checkpoint.

types. Created a binding_type_exception which is thrown when
a bind attempt fails due to mismatched types.
Added helper templates to driver_device to wrap legacy
device read/write handlers into driver_device member functions.
This should help move some things forward until more common
code is converted into proper devices.
Introduce new module devcb2 which contains modernized
versions of devcb. Compared to previous implementation
this one is simpler overall, trampolining calls through
a single internal set of adapter functions. The new
versions are also designed to be specified in the
machine_config rather than in structures, so they are
no longer simple POD types. Additional new/changed
features:
* reads and writes can map to delegates for line or 8/16/32/64-bit
* reads and writes can map to an I/O port
* reads can be mapped to a constant value, with or without logging
* writes can be mapped to a device's input line
* all reads/writes can have a shift, mask, and/or xor applied
* devices can opt to make the functions safe-if-NULL when resolving
* only member function types are supported
Rewrote the YM2151 interface to be fully modernized, and
removed the ym2151_interface struct in favor of inline configs
using the new devcb2 mechanism. In many cases, removed
no longer needed trampolines, instead taking advantage of
direct support for input line writes.

non-templatized helper class so that the code can live
co-located, rather than invading device.h.
Changed the read/write delegates to derive from
device_delegate. Updated the address map macros to create
these properly.
Removed remnants of the old AM_BASE/SIZE macros from the
memory system.

device_delegate which wraps a regular delegate and includes
a string pointer to a device tag, which can be simply
resolved later. Converted the screen_update delegates to
to be based on this. Changed the mechanism by which screen
formats are auto-deduced. Converted SCREEN_EOF to use these
delegates as well, so now there is MCFG_SCREEN_EOF_STATIC/
DRIVER/DEVICE just like MCFG_SCREEN_UPDATE.

a limited capacity (e.g., for devices), but the existing copy-and-rebind
code would just cast the bound object without verifying the pointer was
of the correct type or pointing to the correct class in the hierarchy.
Objects that are late-bound must be derived from the delegate_late_bind
class at some point so that a dynamic_cast from delegate_late_bind to the
appropriate type succeeds.
Updated the address map and custom NVRAM handlers to do the right thing
with their re-binding.

cases, we can get rid of the postload function entirely and just
call directly to the target function. Drivers eventually should
just override device_postload() instead of registering for callbacks.

them more flexible and simpler to use. Got rid of the proto_delegates
altogether in favor of supporting delegates that are bound to NULL
objects. Added a front-end template that supports "natural" syntax
favored by libraries like boost. Added support for static functions
that take reference parameters instead of pointer parameters for the
object type. Updated all delegate users in the system to the new
syntax. [Aaron Giles]
Changed the DIRECT_UPDATE_HANDLER to take a machine reference like
everything else in the system. Updated all users. [Aaron Giles]
Changed the FUNC() macro to automatically put an & in front of the
item passed. In general this works transparently, however it does have
the nice side-effect of catching situations where a variable is passed
instead of a function name. Fixed those cases to push the naming
upstream so that the name is now provided properly. Also added a
FUNC_NULL macro since FUNC(NULL) no longer works. [Aaron Giles]

supporting cleaner implementations of drivers in the explicitly OO world.
Expect a follow-on of several more changes to clean up from this one, which
deliberately tried to avoid touching much driver code.
Converted address_space to a class, and moved most members behind accessor
methods, apart from space->machine and space->cpu. Removed external references
to 8le/8be/16le/16be/32le/32be/64le/64be. All external access is now done via
virtual functions read_byte()/read_word()/etc. Moved differentiation between
the endianness and the bus width internal to memory.c, and also added a new
axis to support small/large address spaces, which allows for faster lookups
on spaces smaller than 18 bits.
Provided methods for most global memory operations within the new address_space
class. These will be bulk converted in a future update, but for now there are
inline wrappers to hide this change from existing callers.
Created new module delegate.h which implements C++ delegates in a form that
works for MAME. Details are in the opening comment. Delegates allow member
functions of certain classes to be used as callbacks, which will hopefully
be the beginning of the end of fetching the driver_data field in most
callbacks. All classes that host delegates must derive from bindable_object.
Today, all devices and driver_data do implicitly via their base class.
Defined delegates for read/write handlers. The new delegates are always
passed an address_space reference, along with offset, data, and mask. Delegates
can refer to methods either in the driver_data class or in a device class.
To specify a callback in an address map, just use AM_READ_MEMBER(class, member).
In fact, all existing AM_ macros that take read/write handlers can now accept
delegates in their place. Delegates that are specified in an address map are
proto-delegates which have no object; they are bound to their object when
the corresponding address_space is created.
Added machine->m_nonspecific_space which can be passed as the required
address_space parameter to the new read/write methods in legacy situations
where the space is not provided. Eventually this can go away but we will
need it for a while yet.
Added methods to the new address_space class to dynamically install delegates
just like you can dynamically install handlers today. Delegates installed this
way must be pre-bound to their object.
Moved beathead's read/write handlers into members of beathead_state as an
example of using the new delegates. This provides examples of both static (via
an address_map) and dynamic (via install_handler calls) mapping using delegates.
Added read/write member functions to okim6295_device as an example of using
delegates to call devices. Updated audio/williams.c as a single example of
calling the device via its member function callbacks. These will be bulk
updated in a future update, and the old global callbacks removed.
Changed the DIRECT_UPDATE_CALLBACKs into delegates as well. Updated all users
to the new function format. Added methods on direct_read_data for configuring the
parameters in a standard way to make the implementation clearer.
Created a simple_list template container class for managing the common
singly-linked lists we use all over in the project.
Many other internal changes in memory.c, mostly involving restructuring the code
into proper classes.
